Application filed. April 12, 1920. I Serial No. 373,234.

To all whom it may concern: I lie it known that I, RALPH BLACK, a citizenof the United States, and resident of the city of New York, borough of Bronx, in the' county and State of New York, have invented a new and Improved Spool-Rack, of

which the following is a full, clear, and exact description.- 1

This invention relates to spool racks and has particular relation to an improvement in spool racks designed fonusein connection with warping mills or weaving machines.

Devices of this character which are now in general use, are so constructed and of such a limited capacity that when the maximum number of racks are arranged in front of a warping mill or weaving machine, it

standard forms of spool racks: The maximum capacity of the largest rack now in use, accommodates 336 spools and the width of said racks is such that it is impossible to arrange and operate more than two racks in front of a warping machine; therefore, the maximum number of spools which can now be run under the present system is twice 336 or 672 spools. As the maximum width of cloth woven is approximately 180 inches requiring 5040 warp threads, it"necessitatesthe running of said threads on in-eight sections to obtain the required number of threads for the maximum width ofcloth;

The principal object therefore, of the present invention is to provide a spool rack which is so constructed and designed as-to' permit of the combined use of a sufiicient number of racks in connection witha warping mill or a weaving machine as to run on the warping millsimultaneously the required number of threads for'the maximu width of cloth in one operation. f

Another object of the invention is to provide a spool rack which is adjustable in width in order to suit various conditions and render the same capable of use singly or combined with other racks of the same construction for various widths of warping tended.

rack.

mills and weaving machines up to and including the maximum.

A further object of the invention is to prov de a spool rack which permits ofthe running ofthe threads into a weaving machine, or directly onto the warping mill or beam A still further object of the invention is to provide a spool rack of the character described which issoiconstructed as to minimize the space required for a maximum number of spools which are so arranged as to permit of the runningof the threads therefrom .onto a warping mill, a beam or direct into a weaving machine without the interference of the threads with each other.

Another ob ect of the invention is-to provide a. spool rack which is capable of folding in order to renderthe same compact .when not 1n use.

A further ob]ect of the invention is to provide a spool rack which is simple in construction, inexpensive to manufacture, strong and durable and which is thoroughly efficient forthe purpose for wlnch it is in- Vith these and other objects. in 'view, some of which Wlll be more apparent as the nature,

purpose and operation-is better understood fromthe following description and claims,-

reference ismade'to the accompanying drawingsforminga part of this application and in which.. I

' Figure 1 is a side elevation of a rack constructed in accordance with the invention. Fig. 2 is a plan view thereof.

'Fig. 3 is a .detail view of the collector lo'raclret removed from the rack. I

Fig. is an enlarged fragmentary detailed perspective view of the front standard and the end standards of the side sections of the Fig; 5' is a fragmentary end vie of one of the side sections of therack illustrating in dotted lines the method of removingor applying a spool to the rack.

Referring to the drawings by characters of reference which denote like parts throughout the several views thereof, 10 and 11 des ignate identical frame sections or wings each i of which includes a rear vertical standard 12, av central vertical standard 13 and a forward vertical standard 14 which may be secured together in spaced relation by any suitable means. The sa d standards are here illustrated as of rectangular formation in support the longitudinal spindle bars 17 portions of said links. ment it will be seen that the free ends of the cross section and are each provided with vertically spaced outwardly extending shelves 15, bifurcated at their outer ends, said bifurcations constituting hinge knuckles 16. The said shelves 15 are preferably arranged in horizontal alinement and are 1 designed to which are eachformed with a projection 18 constituting a hinge knuckle. The said projection 18 is longitudinally apertured and is adapted to lie between the furcations 16 which are also longitudinally apertured and adapted to aline with the aperture in the extension 18 for the reception of a hinge pin 19 to swingingly associate said spindle bars with the shelves. By this arrangement it will be seen that the spindle bars serve as a means of connection between the vertical standards 12, 13 and 14. The forward standards 14: of each frame section are hingedly secured as at 20 to a common front standard 21. "The front standard 21 and the central and rear standards 12 and 13 are preferably provided with casters 22 at their lower ends to permit the rack to be readily transported from place to place. The spindle bars 17 are each provided with a plurality of longitudi nal. spaced upstanding spindles 23 to IGCGlXB the usual spools. ,As the spindle bars are superposed or arranged-in vertical alinement, it is necessary' that the same be swung at an angle to permit of I the application or removal of the spools from the spindles and it is therefore obvious that the hinged connection between the spindle bars and the shelves 15 serves as a means to permit of such a swinging movement.

accidental dumping of the spools from said spindle bars, a plate 2 4 is secured to the end o'feach shelf of the rear standard 12 and the same is provided with an arcuate slot 25 which receives a trunnion 26 extending from dlebars rest upon the shelves 15 and when 3 so arranged the upper extremities of the spindles of the rack immediately below are disposed thereunder to prevent possibility of i the spools riding upward and off of the end of said spindles. The free extremities of the frame sections 10 and 11 are adjustablyconnected to-each other through the medium of the slotted links 28 which are pivoted as at 29 to the inner sides of the rear standards 12, said adjustment being effectediby means of a set screw 30 passed through the slotted By this arrangeframe sections 10 and 11 are relatively adjustable to vary the width of the rack to suit In? order to provide means to limit the outward swinging movement of the spindle bars whereby'to prevent ters Patent is various conditions. In order to provide means for guiding the threads from the spools, guide bars 31 are provided and secured transversely to the front end of the front standard 21. The guide bars 31 preferably include relatively separable sections,.

the inner slotted ends 32 of which are received in the notches 3 in said front standard. A set screw 34 passed'through the slotted extremities 32 serves to removably and adjustably secure the guidebar sections to each other and to the front standard. The i said guide bar sections are provided with a plurality of apertures 35 through which the threads are passed. A collector bracket 36 is secured to the front standard as illustrated and receives at its free forward end the frame 37 which is provided with a depending stud 38 which normally is received by the ofthe combined use of a maximum number of racks in connection with a single warping mill or weavingmachinewithout the possible interference of the threads. When not in use it is obvious that by loosening the set screw- 30 the frame sections may be arranged substantially parallel to each other tooccupya minimum amount of storage space.

From the foregoing descriptionand the appended drawings, it. will be seen that a single and preferred embodiment of the inventionhas been illustrated and described,

but it is to be understood that no limitation is made to the precise details of construction as variations and modifications. which fall within the scope of the appended claims may be resorted to when found expedient.

Having thus described my invention,'what I claim as new and desire to secure by Let- 1.
